Bill before tax and tip will be generated by the original prices of main courses . The total bill is of $84.96

Given, prices of main course at cafe .

The total bill without applying the coupon for that we simply need to add respective costs of main course and drinks bill.

Just adding all the costs to find the bill:

= $(13.99 + 16.99 + 19.99 + 21.99 + 12)

=$84.96

Now since the question asks not to apply coupon and tip so the bill will remain as it is .

Answer:

Don't come at me if I'm wrong, but I think it's y=-3/4x-1 1/3

Step-by-step explanation:

1) you have to subtract 3x from both sides (this makes it 4y=-3x-4)

2) you then divide by 4 on both sides (it will become y=-3/4=4/3)

3) then you simplify the fractions (it becomes y=-3/4x-1 1/3)

Asia is a chef in a restaurant. To prepare for dinner service, she chops 7 1/2 onions in 1/6 of an hour. Asia's rate of chopping onions is 30 onions per hour.

From the information given;

So, the onion is given in mixed fraction which can be converted to an improper fraction as: [tex]\mathbf{\dfrac{15}{2}\ onions}[/tex]

Now,

We can cross multiply the above two equations to determine the number of onions Asia will chop per hour as follows:

[tex]\mathbf{(x) \times \dfrac{1}{6} \ hours = \dfrac{15}{2} \ onions \times 1 \ hour}}[/tex]

Making (x) the subject of the formula:

[tex]\mathbf{(x)=\dfrac{ \dfrac{15}{2} \ onions \times 1 \ hour}{ \dfrac{1}{6} \ hours }}}[/tex]

[tex]\mathbf{(x)={ \dfrac{15}{2} \ onions } \times { \dfrac{6}{1} }}}[/tex]

(x) = 15 onions × 3

(x) = 30 onions per hour.

Therefore, Asia's rate of chopping onion is 30 onions per hour.

If Asia chops 7 1/2 onions in 1/6 hour, therefore, using proportion, the rate of chopping onions per hour is: 45 onions per hour.

Applying the knowledge of proportion and fractions, we can determine Asia's chopping rate of onions per hour.

Given:

Using proportion, we have the following:

[tex]7\frac{1}{2} = \frac{1}{6} \\\\x = 1[/tex]

[tex]\frac{1}{6} \times x = 7\frac{1}{2} \times 1\\\\\frac{x}{6} = \frac{15}{2}[/tex]

[tex]\frac{x}{6} = \frac{15}{2}\\\\x = \frac{15}{2} \times 6\\\\x = 45[/tex]

Therefore, if Asia chops 7 1/2 onions in 1/6 hour, therefore, using proportion, the rate of chopping onions per hour is: 45 onions per hour.

A store charges $414 for a small refrigerator, the price consists of the refrigerator's original cost to the store plus a profit 15% what was the refrigerator's original cost to the store?

Step one:

given data

we are told that the price of the small refrigerator contains both the original price and 15% profit

mathematically

$414= original price + 15% profit

Step two:

let us solve for 15% of 414

=(15/100)*414

=0.15*414

=$62.1

This shows that the profit is $62.1

let the original price be x

$414= x + 62.1

solve for x

x=414-62.1

x=351.9

The refrigerator's original cost to the store $351.9

Answer:

15

Step-by-step explanation:

Since it goes 30 in 2 seconds, we need to divide 30 and 2 and end up with 15.

To make sure our answer is correct we know that 15 is one second, so we can add 15+15= which will give us 30, and will also land at 2

The speed of the scooter is 15 feet per second.

To calculate the speed of the scooter in feet per second, you can use the formula:

Speed = Distance / Time

The distance traveled by the scooter is 30 feet, and the time taken is 2 seconds.

Plugging these values into the formula, we get:

Speed = 30 feet / 2 seconds

Speed = 15 feet/second

Therefore, the speed of the scooter is 15 feet per second.

Answer

y=7x+2

Step-by-step explanation:

you have your slope already so keep slope but remove 5 and turn it into b in order to solve for new equation ...

y=7x+b

sub in (3,23) in your equation

23=7(3) +b

23=21 +b

23-21=b

2=b

your new equation should be y=7x+2

Answer:

y=-1/7+23 3/7

Step-by-step explanation:

Since it's parallel you take the y=7x+5 and the 7 is turned into -1/7(to find what's PARALLEL)

Now you put it into point slope formula to get: y-3=-1/7(x-3)

Simplify the equation.

Step-by-step explanation:

I DID THE TEST

The required explanation which is best for the solution of the given equation is option C.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

We are Given a system of equations,

y = −2x + 3                 (1)

y = −4x − 1                   (2)

The slope of equation 1

m = -2 and y-intercept  = 3

Also The slope of equation 2

m = -4 and the y-intercept = -1

So, From option that matched the calculation

Therefore, "Graph the first equation, which has slope = −2 and y-intercept = 3, graph the second equation, which has slope = −4 and y-intercept = −1, and find the point of intersection of the two lines."

Thus, the explanation that is best for the solution is given by Option C
